Entanglement quantification in atomic ensembles
Matteo Fadel, Ayaka Usui, Marcus Huber +2
Entanglement measures quantify nonclassical correlations present in a quantum system, but can be extremely difficult to calculate, even more so, when information on its state is li…
Nuclear spin squeezing in Helium-3 by continuous quantum nondemolition measurement
Alan Serafin, Matteo Fadel, Philipp Treutlein +1
We propose a technique to control the macroscopic collective nuclear spin of a Helium-3 vapor in the quantum regime using light. The scheme relies on metastability exchange collisi…
Bounding the fidelity of quantum many-body states from partial information
Matteo Fadel, Albert Aloy, Jordi Tura
We formulate an algorithm to lower bound the fidelity between quantum many-body states only from partial information, such as the one accessible by few-body observables. Our method…
Number-phase entanglement and Einstein-Podolsky-Rosen steering
Matteo Fadel, Laura Ares, Alfredo Luis +1
We use the uncertainty relation between the operators associated to the total number of particles and to the relative phase of two bosonic modes to construct entanglement and Einst…
Entanglement between identical particles is a useful and consistent resource
Benjamin Morris, Benjamin Yadin, Matteo Fadel +3
The existence of fundamentally identical particles represents a foundational distinction between classical and quantum mechanics. Due to their exchange symmetry, identical particle…
Does a large quantum Fisher information imply Bell correlations?
Florian Fröwis, Matteo Fadel, Philipp Treutlein +2
The quantum Fisher information (QFI) of certain multipartite entangled quantum states is larger than what is reachable by separable states, providing a metrological advantage. Are…
